Need help just found cold intake caused some wear on the ac line which caused a leak on my line don't know the name of it but I know it's not the one you add freon too it's the one right next to it please help want to change it out myself

 

I moved this to a new thread. You were at the end of another that didn't really apply to your issue.

Can you post a pic of the line? I'm trying to understand which one it is. Also, some will not like this, there are "ac compression" fittings/repairs you can do without replacing the entire line. You just need to know/measure the line diameter.....google Dorman 800-640, this is a 5/8 line repair.
